[0035] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will make further detailed description to the utility model combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0036] The utility model provides a kind of thin film material's take-up and pay-off control device, as shown in Figure 1 Described in the utility model, the device includes pay-off mechanism 100, pay-off buffer mechanism 200, tension idler mechanism 300, film clamping mechanism 400, film pulling buffer integrated mechanism 500 and take-up mechanism 600;Thin film material W is wound in the pay-off mechanism 100, and in turn bypasses the pay-off buffer mechanism 200, film material processing position A, the film clamping mechanism 400, the film pulling buffer integrated mechanism 500 and the take-up mechanism 600, and finally in the take-up mechanism 600 Winding material is collected.

[0037] The pay-off mechanism 100 is used to release a certain length of thin film material W periodically. Usually, it is released by using the time in the thin film material processing process, so as to prepare for providing thin film material.

[0038] The pay-off buffer mechanism 200 is used to first buffer the thin film material W released by the pay-off mechanism, and passively release the thin film material W when the film pulling buffer integrated mechanism 500 pulls and secondly buffers the thin film material. In this embodiment, the pay-off buffer mechanism 200 includes a cylinder, a movable pulley, a sensor and two receivers, the thin film material bypasses the movable pulley, and the movable pulley is driven by the cylinder to reciprocate along a first direction, so as to realize buffering and releasing the thin film material. The receivers are arranged at the two endpoints of the reciprocating movement of the movable pulley, and the sensor is arranged at the moving end of the movable pulley or the cylinder, and the travel position of the movable pulley is identified by the cooperation of the sensor and the receiver, so as to control the cylinder. The first direction is determined after the path of the thin film material winding, and is set for the purpose of buffering and releasing, without creative labor. Of course, the connection relationship in the pay-off buffer mechanism is not limited to this, as long as it can realize its corresponding function.

[0039] The tension idler mechanism 300 is an optional mechanism, which is arranged between the film material processing position and the film clamping mechanism 400, and is used to tension the passing thin film material.

[0040] The film clamping mechanism 400 is an optional mechanism for clamping the film material W when the film material W is being processed, and releasing the film material W when the film pulling and caching integrated mechanism 500 pulls and caches the film material. The film clamping mechanism 400 can further ensure that the film material W does not move when the film material W is being processed, improving the accuracy of the position of the film material W.

[0041] The film pulling and caching integrated mechanism 500 is used to passively release the second cached film material W when the material winding mechanism 600 is winding, and to pull and cache the film material W after the film material is processed.

[0042] The material winding mechanism 600 is used to wind the second cached film material W of the film pulling and caching integrated mechanism 500 during the processing of the film material.

[0043] In addition, idler wheels 700 can be added on the path of the film material W according to actual needs, for example, to change the transmission direction of the film material W to match the setting position and direction of each mechanism.

[0044] The first cache and the second cache are only used to describe and distinguish the execution subject and action of caching, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0045] Further, the structure of the film pulling and caching integrated mechanism 500 is as shown in Figure 2 and Figure 3 , including a driving shaft module 501, a roller module 502, a synchronous belt 503, a driven shaft 504, a motor reducer module 505, and a main support plate 506.

[0046] The driving shaft module 501 includes a driving shaft, which is fixed to the upper part of the main support plate 506 through a bearing. The two ends of the driving shaft are connected to the driven shaft 504 through the synchronous belt 503, and the driven shaft 504 is driven to rotate synchronously with the driving shaft through the synchronous belt 503.

[0047] The drum module 502 is arranged in parallel with the driving shaft, and two ends of the drum module 502 are fixedly connected with the synchronous belt 503, so that the drum module reciprocates between the driving shaft and the driven shaft. The middle part of the drum module is a drum for winding the film material. Specifically, the drum module 502 comprises a drum 5022 for winding the film material and an adapter plate 5021 located at two ends of the drum 5022. The adapter plate 5021 is fixedly connected with the synchronous belt 503, so that the drum module 502 reciprocates between the driving shaft and the driven shaft 504. More specifically, the main support plate 506 is provided with a sliding rail 5091, and the sliding rail 5091 is connected with a sliding block 5092 which can move along the sliding rail. The drum 5022 is a movable pulley drum, and two ends of the movable pulley drum are connected with the adapter plate 5021. The adapter plate 5021 is fixedly connected with the sliding block 5092. The synchronous belt 503 is an annular synchronous belt which is sleeved on the driving shaft 5011 and the driven shaft 504. A part of the synchronous belt 503 is embedded between the adapter plate 5021 and the sliding block 5092. Since the synchronous belt is made of flexible material, the drum 5022 can move up and down along the sliding rail 5091 under the driving of the synchronous belt by increasing the sliding block 5092, so that the drum is not easy to shake, and the position accuracy of the film storage is further improved.

[0048] The motor reducer module 505 comprises a motor for driving the driving shaft to rotate. The motor is used for driving the driving shaft to drive the drum module to store the film material and to control the tension of the driving shaft when the second stored film material is released. Specifically, when the film storage integrated mechanism 500 stores the film, the motor is in a position mode to drive the driving shaft to rotate, so that the drum module 502 moves linearly upward. When the material winding mechanism 600 winds, the drum module 502 moves downward under the force of the film material W, and the motor is in a constant torque mode to control the tension of the driving shaft. The motor reducer module itself is a conventional mechanism, the position mode and the constant torque mode are two different working modes of the motor in use, and the application protects the combination innovation between the motor reducer module and other structures after the motor reducer module is applied in the field.

[0049] Further, the film clamping mechanism 400 has the structure as shown in Figure 4As shown, including the base plate 401, pressure bar 402 and drive mechanism 403; wherein the base plate 401 and pressure bar 402 are arranged in parallel, the film material W is provided between the base plate 401 and the pressure bar 402, the two ends of the pressure bar 402 are driven by the drive mechanism 403 to move along the direction of approaching or away from the base plate 401, so as to clamp or release the film material. In this embodiment, the drive mechanism 403 is a pneumatic cylinder, the two ends of the base plate 401 are provided with through holes, the pneumatic cylinder located below the base plate 401 passes through the through hole and is fixedly connected with the two ends of the pressure bar 402 above the base plate 401, with the extension and contraction of the pneumatic cylinder, the pressure bar 402 moves up and down, and when it moves downward, it presses the film material, and when it moves upward, it releases the film material. The drive mechanism can also use other devices with reciprocating motion driving function, such as hydraulic cylinder. In order to avoid damage to the film material, the contact surface between the pressure bar 402 and the film material is made of rubber.

[0050] The movement process of this embodiment is as follows:

[0051] When the film material starts to be processed, the pneumatic cylinder of the film clamping mechanism 400 drives the pressure bar to press the film material, so that the film material cannot move, at this time the pay-off reel mechanism 100 starts to release a certain amount of film material, the pay-off buffer mechanism 200 buffers the film material released by the pay-off reel mechanism 100 upward; the take-up reel mechanism 600 starts to wind, and the film pulling and buffering integrated mechanism 500 releases the buffered film material under the "constant torque mode" of the motor. When the film material starts to switch (switching means that the processed film material is wound backward, and the unprocessed film material moves to the film material processing position), the pneumatic cylinder of the film clamping mechanism 400 drives the pressure bar to release the film material, the pay-off reel mechanism 100 remains stationary, that is, the motor in the pay-off reel mechanism 100 does not work at this time, the pay-off buffer mechanism 200 is passively released under the condition that the film material is pulled downward; the take-up reel mechanism 600 remains stationary, the motor of the film pulling and buffering integrated mechanism 500 is switched to "position mode", which drives the roller to pull the film upward, so that the film material in the film material processing position A is accurately switched to the next section according to the fixed interval, and a certain amount of film material is buffered in the film pulling and buffering integrated mechanism 500. Thus, a complete cycle is completed.

[0052] That is, during the processing of the film, the motor in the film pulling and buffering integrated mechanism 500 is in a constant torque tensioning state. During the film processing, the motor in the film pulling and buffering integrated mechanism 500 is in a power state.

[0053] More specifically, when the film is being processed, the motor in the motor reducer module 505 is in "constant torque mode", the film material being wound by the take-up reel mechanism 600 is pulled downward, at this time the roller module 502 is connected with the driving shaft module 501 through the synchronous belt 503 (this structure is more conducive to achieving that the film material is pulled downward when the roller module is wound by the take-up reel 600), the motor in the motor reducer module 505 can keep a certain tension of the roller module 502, so that the film material is in a tension state when being wound. When the film material starts to switch, the roller module 502 is at the origin position of the stroke at the position sensor 507, the motor in the motor reducer module 505 is in "position mode", the motor reducer module 505 drives the roller module 502 to move upward through the driving shaft module 501 and the synchronous belt 503, and realizes the material buffering.

[0054] According to the above movement process, the embodiment mainly includes two states in the film material processing process:

[0055] State one: when the film material processing position A is processing the film material, the film clamping mechanism 400 is in a state of clamping the film material, so as to ensure that the film does not move when the film material is processed. The pay-off reel mechanism 100 is in a state of actively releasing the film material, the pay-off buffer mechanism 200 is in a state of buffering the film material, the take-up reel mechanism 600 is in a state of actively taking up the material, and the film pulling and buffering integrated mechanism 500 is in a state of passively releasing the film material (the motor is in constant torque mode, which is used for providing tension control to avoid slipping).

[0056] State two: after the film material processing position A completes the processing of the film material, switching needs to be performed, at this time the film clamping mechanism 400 is in a state of loosening the film material, so as to ensure that the film material can move normally. The pay-off reel mechanism 100 and the take-up reel mechanism 600 are both in a state of stopping, the film pulling and buffering integrated mechanism 500 is in a state of actively pulling the film and buffering (the motor is in position mode, which is used for providing power), and the pay-off buffer mechanism 200 is in a state of passively releasing the film material, so that the unprocessed film material moves to the film material processing position A and the processed film material can move backward to the film pulling and buffering integrated mechanism 500 for buffering.

[0057] It should be noted that, since the device has two states, the mutual positional relationship and the motor mode change in the two states. Therefore, the utility model protects the positional relationship of each mechanism and the positional relationship of each component in the mechanism and the mode in the two states, rather than a control method.

[0058] The utility model also protects a film material processing equipment, including film material processing position and the film material's take-up and pay-off control device.

[0059] It should be understood that modifications or variations can be made according to the above description by those of ordinary skill in the art, and all such modifications and variations are intended to be within the scope of the present application as defined by the claims appended hereto.
